2024 GMC Sierra HD unveiled with new design and more powerful turbodiesel V8

The 2024 Chevrolet Silverado HD made its debut in September 2022, so it was only a matter of time before the GMC Sierra HD received a similar round of updates. Unveiled online, the truck gains a new-look design and a more powerful turbodiesel V8, among other changes. GMC developed the Sierra HD primarily for towing and hauling so the most significant changes are found under the hood. The available 6.6-liter turbodiesel Duramax V8 engine now develops 470 horsepower at 2,800 rpm and 975 pound-feet of torque at 1,600 rpm, figures that represent increases of 25 and 65, respectively, over the 2023 model and that match the 2024 Silverado HD's. GMC notes it increased low-end torque by about 25% by fitting a new turbocharger. The V8 spins the rear or the four wheels via a 10-speed automatic transmission.  On the gasoline side of the spectrum, the 6.6-liter V8's output stays flat at 401 horsepower and 464 pound-feet of torque. It's now bolted to a 10-speed automatic transmission, and replacing the 2023 truck's six-speed lets the engine run closer to its peak power for longer periods. Here again, rear-wheel-drive comes standard and a part-time four-wheel-drive system is available across the entire line-up. Properly equipped, the 2024 Sierra 2500 HD Crew Cab can tow up to 21,900 pounds. The standard 2500 HD's towing capacity checks in at 22,500 pounds (a 4,000-pound improvement), and the 3500 HD is capable of towing up to 36,000 pounds — that's nearly 13 Subaru BRZs. Buyers have a dizzying selection of trim levels and body styles to choose from. The range includes Regular, Extended, and Crew cabs as well as seven trim levels called Pro, SLE, SLT, AT4, AT4X, Denali, and Denali Ultimate, respectively. The AT4X variant will not be available at launch, and the Denali Ultimate is new for the 2024 model year. Additionally, 3500 HD models can be ordered with dual rear wheels. What the truck looks like depends on the trim level. Broadly speaking, designers drew a more angular front end with a new-look grille, sharper-looking lights, and a redesigned bumper. New wheels are part of the update as well; the 3500 HD dually gets 18-inch polished aluminum wheels, and 22-inch units are optional on single-rear-wheel trucks. Finally, the color palette grows with six optional shades called Titanium Rush Metallic, Sterling Metallic, Volcanic Red Tintcoat, Redwood Metallic, Meteorite Metallic, and Downpour Metallic, respectively.

2021 GMC Yukon configurator now open for play-money builds

The 2021 GMC Yukon configurator is open for real and imaginary business. It's missing a number of important options, though, like the AT4 trim and the Premium Capability Package that installs the Air Ride Adaptive Suspension, so the configurator is best suited for practice runs at the moment. Playing our usual game, we started with a livery build in base SLT 2WD trim for an airport shuttle to compare to the livery 2021 Tahoe we built a few days ago. Same as with the Chevy, the GMC offers nine exterior colors. Opposite to the Chevy, the GMC makes you pay for every color except Summit White. Our Onyx Black selection added $195, five colors cost $495, Cayenne Red Tintcoat costs $695, and the super gonzo White Frost Tricoat runs $1,095. We plumped for the SLT Luxury package's driver assistance and convenience features like memory settings for the front passengers, powered seating for the second row, a split third row, the Rear Seat Media Package, and a console lockbox. What began as $59,095 after destination — $4,000 more than the 2021 Tahoe — ended at $64,445, just $2,165 more than our livery Tahoe because the Yukon packages more kit.   The amounts add up a lot quicker at the top end. Our regional rep with a fat bonus check started with a $72,295 Yukon Denali 4WD in the $495 Pearl Beige Metallic with a Teak and Light Shade interior. The $6,500 Denali Premium Package normally costs $500 more, and who can resist a sale? At about 9% of MSRP, it's not a negligible option, but it includes the $1,780 Advanced Technology Package, the $1,500 panoramic sunroof, and a set of 22-inch wheels that are normally $2,995. Since the bonus was big enough to replace the two-year-old jet skis in the garage, our rep added the $465 Max Trailering Package and that automatically appends the ProGrade Trailering features. Put in the Rear Seat Media Package to occupy the kids, locking armrest storage to protect stuff from the kids, and hook up a set of illuminated GMC badges for $535 to wow oncoming vehicles, and the total comes to $83,320. That's more than $10,000 in options without the least effort. However, there aren't any big-money options left to add except a $1,499 rooftop tent.     GM Authority wrote about the package combinations necessary to unlock the Air Ride Adaptive Suspension on the AT4 or Denali trims. Summed up, the check boxes add $3,410 to the price of an AT4, $3,755 to the price of a 2WD Denali, and $6,015 to the price of a 4WD Denali.

2022 Chevy Tahoe, Suburban and GMC Yukon get updated transmission

General Motors' full-sized SUVs have slipped in one more change before the year turns. GM Authority reports that the 2022 Chevrolet Tahoe and Suburban, and the 2022 GMC Yukon and Yukon XL equipped with gas V8 engines, will pick up a revised ten-speed automatic transmission. The new unit carries RPO code MHS, and Chevrolet communications rep Catherine Scales told GMA the updated gearbox "allows our manufacturing and dealer teams to more easily align the specific calibration needed for the transmission and can enable OTA updates in the future." It seems GM wants to make it easier to update the transmission's tuning and calibration in the future with the automaker's networked Vehicle Intelligence Platform/Global B electronic architecture. The 10-speed auto comes bolted to the 5.3-liter V8 and the 6.2-liter V8. The 3.0-liter inline-six Duramax diesel continues with the 10-speed automatic already in use. To recap the other changes for the full-sizers, we'll start with the 2022 Tahoe and Suburban, which get a new 12.3-inch digital instrument display to replace the former 8-inch unit and physical gauges. Navigation will be standard equipment displayed on the 10.2-inch infotainment touchscreen on all trims barring the base LS. Lane-keeping assist and parking sensors are also now standard, while reverse automatic braking is added to the Enhanced Display and Alert package on the top trims. Finally, the 6.2-liter V8 option is expanded to the Z71, RST and Premier trim levels, but it requires selecting one or more packages on the Z71 and RST. Moving onto the 2022 Yukon, availability of the 6.2-liter V8 expands to the AT4 trim, and the big V8 comes with a shiny pair of exhaust finishers. Redwood Metallic paint joins the exterior color palette, more wheel options are on offer, and illuminated sill plates can gussy up the rocker panels . An Enhanced Trailering Technology Package adds 13 cameras with the option for an interior accessory camera for those with enclosed haulers. On the safety side, expect reverse automatic braking to join the list of available driver assistance features. Inside, the Yukon welcomes the 12.3-inch digital cluster, the Yukon Denali welcomes the power sliding console as a standard feature instead of a $350 option.  Related Video:
